Barcelona goalkeeper Marc-Andre ter Stegen has attributed his team's consecutive shock eliminations from the Champions League to mental failings, rather than tactical shortcomings.
The season before last the Blaugrana held a 4-1 lead from the first leg, before Roma won 3-0 at home in the return fixture to eliminate Barca on away goals.
Last campaign it was Liverpool’s turn to cause red faces in Catalunya, roaring back from a 3-0 defeat in the first leg of their semi-final tie to win 4-0 at Anfield and deny Ter Stegen’s men a chance at European glory.
